This RoMeo BLE controller inherits all functions of Romeo all-in-one controller, on the basis of which it integrates Bluetooth 4.0 wireless communication function. You can describe it as a control board specially designed for robot applications, carrying

This expansion board not only leads to 9 micro:bit onboard GPIO interfaces, but also comes with 4-way motor drives and 8 servo interfaces, of which 4-way motor drives can be reused as 2-way stepper motor drives.

This is a metal geared DC motor w/Encoder. It is a 6V motor with a 34:1 metal gearbox and an integrated quadrature encoder that provides a resolution of 11 counts per revolution of the motor shaft, which corresponds to 341.2 counts per revolution of the g

The DFRobot Relay shield is capable of controlling 4 relays. The max switching power could be DC 90W or AC 360VA. It could be directly controlled by Arduino/DFRduino through digital IOs with external 9v supply.

This is a very popular LCD Keypad shield for Arduino or Freeduino board. It can be directly plug onto the Arudino board, no soldering or fly-wiring needed. A 16x2 HD44780 compatible LCD, White character & Blue backlight.

The Voltage Divider can detect the supply voltage upto 25V. The DFRobot Voltage Divider module is based on resistor divider principle. The voltage detection module allows the input voltage to reduce 5 times. As the Arduino analog input voltage is up to 5V

This module features the MSGEQ7 graphic equalizer display filter.It will give your arduino ears. Sound is broken down into seven frequency bands and the peak level for each band can be read. The seven frequencies measured are as follows: 63Hz, 160Hz, 400H
